Article Citation - WoS: 1Citation - Scopus: 2Exploration of Casson Fluid-Flow Along Exponential Heat Source in a Thermally Stratified Porous Media(Vinca inst Nuclear Sci, 2023) Dadheech, Praveen Kumar; Jat, Ram Niwas; Baleanu, Dumitru; Purohit, Sunil Dutt; Agrawal, PriyankaObjective of the present investigation is intended to study the MHD Casson fluids flow through an exponentially stretching surface. This free convective flow is in-vestigated in thermally stratified porous medium. Also viscosity along with thermal conductivity is varying with temperature. With the exponential decay for the inter-nal heat generation in the region and buoyancy force, the natural-convection is induced. Then the transformed set of equations of the flow after applying suitable similarity solutions were encountered by Shooting Technique in conjunction with the fourth ordered Runge-Kutta method. Outputs illustrates that with increased viscosity parameter an increasing velocity profile is noticed but a decrement is observed for temperature field in entire domain and near the wall for temperature gradient profile. Also with increased Casson fluids parameter decreasing velocity profile is noticed but an increment is observed for temperature field in entire do-main and for temperature gradient profile near the wall.Article Citation - WoS: 14Citation - Scopus: 17Thermal Analysis of Magnetohydrodynamic Viscous Fluid With Innovative Fractional Derivative(Vinca inst Nuclear Sci, 2020) Imran, Muhammad Asjad; Baleanu, Dumitru; Alshomrani, Ali S.; Ahmad, MushtaqIn this study, an attempt is made to investigate a fractional model of unsteady and an incompressible MHD viscous fluid with heat transfer. The fluid is lying over a vertical and moving plate in its own plane. The problem is modeled by using the constant proportional Caputo fractional derivatives with suitable boundary conditions. The non-dimensional governing equations of problem have been solved analytically with the help of Laplace transform techniques and explicit expressions for respective field variable are obtained. The transformed solutions for energy and momentum balances are appeared in terms of series form. The analytical results regarding velocity and temperature are plotted graphically by MATHCAD software to see the influence of physical parameters. Some graphic comparisons are also mad among present results with hybrid fractional derivatives and the published results that have been obtained by Caputo. It is found that the velocity and temperature with constant proportional Caputo fractional derivative are portrait better decay than velocities and temperatures that obtained with Caputo and Caputo-Fabrizio derivative. Further, rate of heat transfer and skin friction can be enhanced with smaller values of fractional parameter.Article Citation - WoS: 7Citation - Scopus: 6The Natural Convective Graphene Oxide Nanofluid-Flow in an Upright Squeezing Channel(Vinca inst Nuclear Sci, 2019) Gul, Taza; Alshomrani, Ali S.; Baleanu, Dumitru; Ullah, Malik Z.The 3-D flow of water based graphene oxide (GO-W) and ethylene glycol based graphene oxide (GO-EG) nanofluids amongst the binary upright and parallel plates is considered. The unsteady movement of the nanofluid is associated with the porous medium and the unbroken magnetic field is executed in the perpendicular track of the flow field. The basic governing equations have been altered using the Von Karman transformation, including the natural-convection in the downward direction. The solution for the modeled problem has been attained by means of optimal homotopy analysis method (OHAM). The influence of the physical parameters on the momentum boundary-layer, pressure and temperature fields is mainly focused. Moreover, the comparison of the GO-W and GO-EG nanofluids under the impact of physical constraints have been analyzed graphically and numerically. The imperative physical constraints of the drag force and heat transfer rate have been computed and conferred. The consequences have been validated using the error analysis and the obtained outcomes have been shown and discussed.
